this invention is to provide i VA11 object of animprovecl `construction for a brush parf A further vobject of an elongated wider loop portion 10 tion of a longer yticl'ilarly ,adapt-edfor Acleaning containers v' such as bottles and jugs. onthe inside.

A further Object of this invention is to provide improvedtmeans for expanding and vcontracting 'a brushlaterally ofv itsrmedian line. 1 v f this vrinvention is to provide improved means formounting brush elements on anexpansible' and contractable frame.-v y lMyinvention consists inthe construction, arrangement and combination of elements hereinafter'` set forth, pointed out in the claims and illustrated drawing, in whichy Figure 1 is a side view of my improved brush, shown closed or contracted in solid lines and expanded in dotted lines. `Figure 2 is a View at right angles to Figurel. Figure 3 is a cross-section on the indicated line 3-3 ofFigure 1. Figure 4 is a crosssection on the indicated linee-@4 of Figure 1.

In the construction of the device as-shown the numeral 10 designates generally a recurved handle, preferably formed of a metal bar having parallel stem portions 10',l 10 formed on the end portion of the bar and at they center ofthe bar, the `sides of the loop portion being substantially 'paralleland the outer `end thereof being arcuate. membersy are provided on opposite sides of the median line of the handle and each frame member is formed of two channel bars of unequal length', the shorter bars being designated by the numerals 11 and 13 and the longer bars being designated by the numerals 12 and 14. -The channel bars of the frame members have their `channels opening outwardly relative to the median line of the brush and one end each of the shorter bars 11, 13 is pivoted to the extremity of one of the arms of the stem portion,

10. 10, while the outer end portion of each shorter Abar is pivoted to the inner end porbarv 12 or 14. Collars 1,5, 16y are mounted on and fixed in spaced rela-v tion tothe stem portion of thehandle and serve to hold the arms '10', 10 in `fixed spaced relation. A. push rod 17 is slidingly mounted in the handle and is confined by the collars 15. 16which, together. withvthe arms10, 10 form a slide bearing there- Application ined ruiyw'ai,

for, andl saidvpush'rod extends *forwardlyv from the collar 16, when the devicejis in contracted position,` outer ends of the `channel ybars, 12, 14. The .push rod is formedlwith an eyevor'loop `18 substantially Y to y the y on its inner endv between the sides of the loop portion 10` of they handle and the diameter of said'eye in the plane of said sides. The forwardend portion ofthe p ushv rod 17 is flattened'inthie planes of the side. margins of the channel bars 11,12, 13 and`r` 14 and connecting rods 19, l20 and 21,122 'are employed pivotally to the channel bars.` The-rods 19 and l2O 'are pivoted attheir rear' ends to the jointsfbetween the channel bars lwhile the rods 21. and 22 are pivoted at their rear yends to thev central portions of the bars 12 and 14. The

forward end portions of the rods 19 and 20 are coincidently pivoted ytothe push rod 17 by a pin 23 intersecting the flattened faces of saidpush rod, vwhilethe forward end portions 'of the rods 21 and 22 are coincidently pivoted` td vthe k forward end portionv rod by a pin 24 intersecting the of the push iattenedfaces of said pushvrod. vision is made for maintaining positions of the bars 12 and 14irrespective Thus pro- `of the spacing of said bars relative to the ypush rod 17.

on the frame members and preferably are` `construct-ed of twisted wirecores lBrush members are mounted y 25, 26 and bristles `27.mounted between the wires constituting'each core.l Rear end portions of lthe cores 25, 26 are extended through and clenched on the inner `faces of the rear portions of the channel bars 11 and 13 while` the forwardend portions of said cores extend through" and are clenched on the inner surfaces of the i outer end portions of the channel bars 12 and 14. The body portions of the cores 25, 26 `draw into the chan-- nels of the bars 11, 12,13 andf14, particu larly when the frame` members are in expanded positions. Any suitable means may be employed for securing the brush elements to the frame imembers. Primarily the brush elementsfproject radially 'asv arcuatebodies outside of the frame members, but inv use they tend to become disarranged and 'extend radially. Varound the cores25, 26 except where prevented by the frame members.

In practical use' the ldevice may be employed generally for brushing Y purposes inl vany condition of expansion oi1 contraction.

l the inner wall'of the cleaned to The device may also be contracted lfully, by pushing the rod 17 outwardly relative to the handle through manual force applied to the eye 18 and, when so contracted it` may be introduced through a restricted necl otra bottle, jug or other container or through either open end of a lamp chimney or globe. After cleaned, the brush may desired degree, by through manual force applied to the eye 18, thereby causing the bristles 27 to engage object to bel cleaned. Thereafter the tool may be rotated, oscillated 'or reciprocated' in the object to be the end of cleansing or polishing the inner-surface of saidobject. It is to be be expanded to any understood that the tool may be employed ldry either with Y 'or withoute cleaning or ypolishing powder, or it may be employed with any desired cleaning or polishing liquid or solution.

' I claim as my invention f 1. A brush comprising a skeleton handle,

being introduced to the device to be pulling the push rod 17y spaced collars on said handle whereby a slide bearing is formed, a push rod slidingly mounted in said handle and adapted for manual l adjustment relative thereto, channel bars pivoted to said handle, other channel bars pivoted to the first channel bars, rods pivotally connecting said push rod to said channel bars andbrush elements mounted on and projecting outwardly from said channel `bars. f v

2. A. brush comprising a skeleton handle having 'a stem and a looped end portion, n spaced collars on said stem portion, a push l rod slidingly mounted in said handle and extending through said collars, jointed frame members pivoted to said handle and extending on opposite sides of said push rods, toggle connections betweensaidpush rod and frame members and brush elements carried by said frame members. i
